Eco-Best Mahimahi from U.S. caught by troll/pole Farmed striped bass Catfish from U.S.	Eco-Worst All shark

This is an Eco-Worst choice. If you decide to eat it, we recommend the following due to elevated mercury levels:

Most shark species are severely depleted. The main reasons for their precipitous decline are:

They are caught accidentally by the thousands and discarded as waste by tuna and swordfish longline fishers.
There is strong demand for their fins in Asia.
Most sharks mature slowly and have few offspring.

Spiny dogfish are especially vulnerable to overfishing, since they have the longest gestation period of any vertebrate (two years).

Serving = 100 g of raw edible food, wild species.
